c) Skirt self-support metallic vertical vessel with the ratio of height H and average diameter D greater than 5.
1.3 Skirt self-support metallic vertical vessel with the ratio of height H and average diameter D no greater than 5 may be designed by reference to Appendix E.
1.4 This Standard is not applicable to the following vertical vessels:
a) Vertical vessel accompanied with bracing device;
b) Coupled in-line vessel or vessel group integrated by operating platform;
c) Vertical vessel with jacket;
d) Cast iron and nonmetallic vertical vessel.
